Is the script executable?

Hi,
I have a cron job running which yum updates all my machines once a day.
All of these work fine.
I also have a cron job which checks for kernel updates every hour and
sends me a message if an updated kernel has been installed. Here is the
relevant script:
--- begin file called check-kernel.sh in my scripts/yum directory---
#!/bin/bash
latestkernel=$(rpm -q kernel |tail -n1|sed -e 's/kernel-//')
#echo "$latestkernel"
if uname -a | grep -qv "$latestkernel"; then
notify-send "Kernel UPDATE on ${HOSTNAME}: Running Kernel is $(uname
-r) but lat est installed rpm is ${latestkernel}; REBOOT required"
fi;
--- end file called check-kernel.sh ---
(A bit wordy, I know.)
I have verified that this is executable and works from the commandline
without any errors.
I have the following set up via crontab -e:
0,15,30,45 * * * * nice -n 19 $HOME/.xplanet/download_xplanet_cloudmap
5 * * * * nice -n 19 $HOME/scripts/yum/check-kernel.sh
The first line downloads cloudmaps for use with xplanet and works just
fine (or appears to) and has done so for aeons.
However, nothing happens (or appears to) for the second line.
What is wrong here?
Many thanks and best wishes,
Ranjan
